Insulin treatment is the mainstay of Type-1 diabetic management and one of the cornerstones in Type-2 diabetes. This treatment is based on multiple daily injections of different types of insulin. Patients follow their endocrinologists' directions by adhering to a set of recommended dosages and formulas, calculated by repeated blood glucose measurements. In order to maintain effective and safe management, glucose measurements are taken before meals and at bedtime, albeit imposing a heavy financial burden on a patient and their support system. For illustration, each disposable glucosemeter strip costs more than a dollar and needs to be replaced routinely 4 times daily, yielding an annual cost of more than $1500 per patient. Insulin dosages necessitate repeated adjustments to meet the patient's changing needs. Variations in food intake, body weight, physical activity, on going medical conditions and mood can impact a patient's insulin needs.
